Patented July 26, 1910.

Application filed January 20, 1910. Serial No. 539,143.

To all whom it may concern:

Be it known that I, WILLIAM E. WnA'rH nus, a citizen of the UnitedStates of America, residing at Frederick, in the county of Tillman andState of Oklahoma, have invented certain new and useful Improvements inOil- Burners, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to oil burners, and the principal object of thesame is to provide a novel type of oil burner in which a thoroughcombustion of the fuel is obtained by the use of steam means beingprovided whereby the steam is generated through the heat from theburner, and means being provided whereby the danger of explosion of thesteam is automatically prevented.

In addition to the foregoing prominent features of the invention, it iscontemplated providing a novel type of burner pan one end of which isprovided with a burner, the burner being surrounded by a sectionalcasing through which the fuel is fed to .the burner, and one portion ofsaid casing. being provided with a compartment through which the fuel ispassed before being delivered to the burner, said compartment beingarranged relatively to the burner so that the heat from the burnerretains said compartment highly heated.

In carrying out the objects of the invention generally stated above itwill be understood, of course, that the essential features of the sameare necessarily susceptible of changes in details and structuralarrangements, one preferred and practical e1nbodi ment of which is shownin the accompanying drawings, wherein Figure 1 is a fragmentaryperspective view of the firebox of a stove showing the improved burnermounted therein. Fig. 2 is a central vertical sectional view taken onthe line 2 2, Fig. 1. Fig. 3 is a detail perspective view of the steamdischarge nozzle forming a part of this invention. Fig. -1 is a verticalsectional view taken on the line fitfl:, Fig. 3. Fig. 5 is a detailvertical sectional view taken on the line 55, Fig. 1. Fig. 6 is a detailView of the check valve for permitting the excess steam to escape fromthe generator.

The improved burner is equally applicable to cooking or heating stoves,and is placedin the firebox 1 of a stove 2 such as is conventionallyshown in the accompanying drawings.

' The burner comprises a pan 3, the bottom of which is flat and providedwith a casing I at its forward end the bottom 5 of which is preferablyat an angle to the bottom of the major portion of the pan. The outer endof said casing is rounded and has its upper portion cut-away, the loweredge of said cutaway portion being provided with a seat 6 and the sidesof said cut-away portion being arranged to provide vertical side guides7.

, A closure 8 is provided for said cut-away portion, said closureconforming to the contour of the casing and having a bottom edge that isprovided with a seat 9 and a flange 10 which are adapted for overlappingengagement with the seat 6 and the seat flange 6 of thebottom edge ofthe cut-away portion, and the vertical sides of said closure beingprovided with flanges 11 which engage the inner surfaces of the sideguides 7. Said closure 8 is also provided with an external handgrip 12by means of which the closure may be readily manipulated to place thesame in position to close the cut away portion of the casing or to beremoved therefrom. At its top, the casing is provided with a raisedguard flange 13 the free edge of the central portion of which iscut-away, and the free edge of the top of the closure 8 at its center iscomplementally cut away, so that an opening 14; is provided thatcommunicates with the interior of the casing and through which fuel isfed.

The inner upper corner of easing 4: is divided into a heatingcompartment 15 by means of the inclined wall 16 which merges into theinner vertical wall of the casing, and said vertical wall, in turn,merges into a flat flange 17 that covers or overlaps, the open end ofeasing 1 that communicates with pan 3. A substantially cup-shaped burner18 is supported within casing 4 by the legs 19, said burner beinglocated directly beneath the fuel opening 1 1'.

The pan 3 is provided with bottom lugs 20 which are provided with athreaded opening for the reception of an adjusting screw 21, the screwsin turn engaging intern-ally threaded tubes 22, thereby providingadjustable supporting legs for the pan by means of which said pan may beadjusted relatively to the grate or bottom of the firebox upon which itis resting.

A fuel supplying pipe 23 has one end in communication with the inlet endof a union 24, said union being provided with a partition plate 25 thatdivides a side outlet 26 into which a pipe 27 extends, said pipe 27being provided with a central, longitudinally arranged partition plate28. Said pipe 27 is open at both ends, and extends into compartment 15.The discharge end 29 of union 24 has a threaded engagement with a feedpipe 30 that is equipped with a controlling valve 31, said pipe 30extending over the top of casing 4 and having a pendent discharge end 32that is arranged directly over fuel opening 14. This arrangement of fuelfeeding means causes the fuel to pass through one side of pipe 27 andenter compartment 15 and leave said compartment through the other sideof said pipe, and be delivered through fuel feeding opening 14 in aheated condition owing to the fact that said compartment has been heatedby the flames from burner 18.

A water supply pipe 33 equipped with a check valve 34 and a controllingvalve 35, has one end portion extending longitudinally over pan 3, saidpipe communicating with the inner end of a water coil 36. The outer endof coil 36 has a pipe 37 extending therefrom that projects through theopen end of easing 4 and passes beneath burner 18 and enters one end ofa nozzle 38 that is provided with a downwardly inclined dischargeorifice 39 which directs the steam discharged therethrough to the bottomof the open end of casing 4. A threaded plug 40 closes a threadedopening that communicates with the interior of the discharge nozzle 38and through which access may be had to the interior of the nozzle topermit the same and its discharge orifice to be cleaned when necessaryor desirable.

As described, it will be understood that the necessary air supply is hadbetween the guard flange at the top of casing 4 and the free edge of thetop of closure 8 to insure combustion of the fuel in the burner 18, andthat the heated products of combustion from the fuel burning flowsthrough the open end of casing 4 and contacts with and highly heats thecoil 36 supported upon pan 3 so that the water entering said coil isconverted into steam. And the steam from said coil is discharged fromnozzle 38 toward the open end of casing 4, which mixes with the burningfuel and causes a thorough combustion of the same, and also causes adraft to be formed through said open end of the casing which directs theheat from the casing to the coil 36.

As an adjunct to the steam generating feature of the invention, meansare provided whereby the surplus steam may be automatically withdrawnfrom the coil 36 so that an explosion is prevented, said meanscomprising a pipe 41 that has one end in communication with the innerend of said coil, and its other end in communication with the checkvalve casing 34 of water supply pipe 33. It will be understood that whenmore steam is generated in coil 36 than can be discharged by nozzle 38,the excess steam will be bypassed through pipe 41 to supply pipe 33, thecheck valve 34 forming the connection between pipes 33 and 41 and beingof the well known inwardly opening type which will readily permit thepassage of the steam to said pipe 33.

What I claim as my invention is 1. An oil burner comprising a burnerpan, a casing at one end thereof, a burner in said casing. means forfeeding fuel to said burner, water coils carried by said pan, means forsupplying water thereto, a discharge nozzle in said casing and incommunication with said coils, and means for by-passing excess steamfrom said coils to said water supply.
